After looking at it again, Luo Chen's heart regained his consideration, and Chao Yijian asked, "Do you think that these hollow pillars may not only be used for up and down passage?"

Yi Jian nodded.

Luochen saw what he thought and got a tacit response, so he said to Qu Yi and Hongni: "These columns in front of us seem to be deep underground, but they may not be horizontally connected, so let's still grope forward as usual." ”

The two of them naturally understood the meaning of Luochen at this moment, but the traces of this horizontal connection have not yet been visible, so it is not good to wander around blindly.

According to what you said, if there is really another horizontal place, this great immortal will look at the posture of turning in the cave in this place, and he will not return to one. We're going to have to prioritize, don't we?"

When Luochen heard this, he turned his head and said to Yi Jian: "Dao Chief, can you lend me that pocket?"

Yi Jian then handed over the bag of things that the red mud had picked up and discarded after being picked up by others.

Luochen took it in his hand, opened his pocket and picked out a few flowers and plants, and then leaned against the column in turn to try it. In the end, one of them was chosen, and a few were taken and distributed to their companions.

Those few didn't know what to do, and asked each other with eye looks.

Luochen said: "Plants and trees are born according to the ground, the root system is downward, and the flowers and leaves are upward, which is because the root system has a geotropic nature, and the stems and leaves have a negative geotropic nature." In the same way, they also have various characteristics such as phototropism and magnetism.

I can't name the flowers and plants that I picked out of the treasure, but its directional magnetism is much more sensitive than that of ordinary plants, and it can always save a lot of trouble by exploring the hidden pipes in the buried rock wall. ”

After listening to this paragraph, the three remembered his movements, and they knew the general meaning. It's just—

Red Clay looked at Luochen with strange eyes and said, "Where did you hear this truth? This great immortal has been with you for a long time, and he has never heard of it......

Luochen was stunned when he heard this, and seemed to be aware of the strangeness of Fang Cai's words. Secretly surprised, he couldn't understand it, so he said, "Maybe it was from which book did you read it in the old days in the Heavenly Cabinet, right? ”

Red mud thinks about it, the heavenly cabinet is the place where the Taiwei Court collects books, and the Taiwei Court is a high-end place in the heavenly realm, and the dust has grown in the heavenly cabinet since childhood, and it is reasonable to read a few books that he doesn't know, so he no longer asks.

Luochen also temporarily put aside the doubts in his heart, held the flowers and plants in his hand, and looked at the front and back channels around the "crab".

When he stopped at a certain position, those curly roots suddenly seemed to be hooked by something, and the branches became obvious, so he said to the other three, "Let's go this way." ”

The three of them did as they were told.

Leaving the "crab" porch all the way deep, there was a fork in the road, and then according to the posture of the flowers and plants curling and stretching, the pace was adjusted in a timely manner.

Red Clay held the plant and followed the dust, because of his own interest, and from time to time deliberately up and down to rub or leave it on the rock wall, watching the roots roll and overlap.

After a while, he couldn't help but sigh to himself: "This thing is a little similar to the finger grass of broken grass." No, it's more like a compass than a grass. ”

As he spoke, he suddenly realized, his eyes were withdrawn from his hands to play, and he complained to Qu Yi and Yi Jian Lao Dao, "Ben Daxian just remembered that it is common for mortal Taoist priests to walk with a compass in their hands, what about the two of you? ”

Qu Yi laughed when he heard this: "Who told you that a cultivator must have a compass in his hand? Besides, I have never worshiped the Taoist gate seriously, so I am not a Taoist." ”

Yi Jian looked even more innocent, and muttered in a low voice: "Although the poor road calls itself 'poor road', in fact, the teacher is the immortal family celestial ......"

Hongni continued to complain as if he hadn't heard it, "You don't allow the use of spells here, if you have a compass in your hand, wouldn't it be more convenient to walk than these flowers and plants?" ”

Luo Chen felt funny when he heard his muttering, and teased behind him: "You love to bully Qu Yi in Su Ri, and now you are also a gentle person with the Taoist chief, and you have another object of spoofing." ”

"Eh, what are you talking about? Who has this great immortal bullied? Isn't this an obvious truth! I'm not wrong, why are you bullying people?!"

Muttered and walked for a while, and suddenly felt that the voices and footsteps in front of him were becoming more and more frequent, and the figures seemed denser than the occasional dodge on the road before, and the red mud consciously closed his mouth.

After lying dormant in the corner for a moment, Luochen pointed to the plant in his hand, and then pointed in the direction where someone had spoken, and gestured to the three.

A few people understood, nodded, and then waited for the few people to leave for a while, and then tiptoed to follow.

The figure followed for a moment, and suddenly saw a brighter beam of light thrown into the corridor, and several people knew that they must have arrived in another open place ahead, so they scattered in the corner to cover it, preparing to explore the truth in the dark first.

Moved in the dark, followed step by step to the entrance, slightly stretched out his head and quietly looked ahead.

I don't know if I don't see it, and I'm shocked when I see it.

I thought it should be the main hall of the cave where the people were hiding underground in the inn, but what I saw was like a place of imprisonment.

Including the road underfoot, the entrances and exits of the passage in several directions in the vicinity are deeply embedded in the rock wall with strong iron fences. To prevent people from trespassing, there are also traps on the fence. Outside the fence, there are two directions that are specially guarded by people with swords.

As for the situation inside the fence, it may not be easy to describe.

Attached to the rock wall was a circle of huge iron buckets, each of which was half-concealed by a withered human head. The inside of the barrel is indistinct, but you can feel that it is emitting a strange smell.

Luochen couldn't tell if it was a cell inside the fence, or if the people in the buckets were prisoners, and he didn't know why they were like this. The only thing that is clear is that behind the iron barrel, inside the rock wall, there should be a pipeline that is connected.

The plant in his hand is vigorously stretching its roots in the direction of the fence.

The people who were followed were probably here for a shift change. After entering through this side of the fence, he circled around a tin barrel, and after some inspection, he came out of the fence from the other direction and stood guard outside the gate.

The person who had been replaced, after muttering a few words to him, turned around and disappeared into the passage over there.

Hongni looked at the half of the human face that was slightly exposed in the iron bucket, and said angrily to the three ventriloquist voices of Luochen: "Ben Daxian said that he met a black shop, right? You see, these people who are locked up are probably the guests who entered the store before us, but I didn't expect to be tortured into this appearance!"
